The 13th Heterogeneous Computing Workshop (HCW 2004) will be held in
Santa Fe, New Mexico, USA, on April 26, 2004, and has been associated with
the International Parallel and Distributed Processing Symposium (IPDPS) for
many years. IPDPS 2004 is sponsored by the IEEE Computer Society,
through the Technical Committee on Parallel Processing (TCPP), and is held
in cooperation with the IEEE Computer Society Technical Committees on Computer
Architecture (TCCA) and Distributed Processing (TCDP), and the ACM Special
Interest Group on Computer Architecture (SIGARCH).

Heterogeneous computing systems are those with a range of diverse computing
resources that can be local to one another or geographically distributed.
The pervasive use of networks and the Internet by all segments of modern
society means that the number of connected computing resources is growing
tremendously. Hence, the opportunity and need for heterogeneous computing
systems to effectively utilize these resources in new, novel ways is
growing concomitantly. This has given rise, for instance, to the notions
of grid computing and peer-to-peer computing. The effective implementation
of efficient applications in these environments, however, requires that
a host of issues be addressed that simply do not occur in "single-chassis"
sequential or parallel machines.
